ELECTRIC SIGNAL-TRANSMITTING APPARATUS.

Application filed April 1-5, 1910. Serial No. 555,605.

To all whom it may concern Be it known that I, Fnnonmoii \V. Cons, of Newton, in the county of Middlesex and State of Massachusetts, have invented an 5 Improvement in Electric Signal-Transmitting Apparatus, of which the following 1s a specification.

This invention relates to electric signaltransmitting devices, and has for its ObJGCt the construction of an improved form of multiple signal-transmitting device adapted to send a number of differentsignals,

preferably with a differentiating signal impulse in connection with some of the sigmils, whereby'the signals may be received upon an electric signal-recorder of any usual or suitable construction, and those signals having a-diiferentiating signal-impulse may cause the operation of 'an'audible alarm,

y This signal-transmitting device is especially adapted to be..nse d in connection with supervisory signal-systems, such as represented in my applications for Letters Patents, Serial Numbers 555,601, 555,602, 555,603 and'555,6 0 -1. I

My invention is embodied in an apparatus adapted to send a code-signal wh ch preferably represents a number to identify its location. The identification number once 0 sent may be termed a round. The different signals are represented by the number of times this identification number is; repeated; as, for instance, the identification number once sent, or one round, will constitute a certain signal; twicesent, or two rounds, another signal; and so on: Each round may be composed of a series of signal-impulses of short duration, and between all, or at least some of the rounds, a prolonged sig- 0 nal -impulse may be employed asthe difi'erentiatingsignal-impulse. In such case the signals on the tape of a recorder w 1ll be represented dots, and the differentiating signal-impulses by dashes.

.The signal transmitting-apparatus embodyingmy invention comprehends the employment of a starting-magnet by Wli1Cl1 1t is release dfoi' caused to operate, and said magnet is connected in an electric circuit '50 which hasseveral branches, each having one or more circuit-closers, foroperating the starting-magnet according t0-the dlflferentsignals to be-sent; yet the apparatus may be otherwise operated. As the different signals are represented by a different number of rounds, the operation of the transmitter, when released to send any of them. will be governed according to the number of rounds to be transmitted by it. and, for this pur- :pose, signal-determining devices are emplayed, adapted-to be operated by the transmitting mechanism in conjmiction or coiip- ?eration with the means operated to release 5 it, to determine the number of rounds which ;shall be transmitted in response to the pari ticular releasing-means operated.

For simplicity of construction the starting-magnet maybe employed to serve also @as the controlling-magnet for the trans- Emitting mechanism-and, in such case, the

imagnet, or the branch-circuits for said circuit-closers will be respectively controlled Eby the signaldetermining devices; as, for finstauce, the circuit-closer in one branch of the circuit of the starting-magnet may be operated momentarily and be self-restoring, rand, in such case, the starting-magnet will be momentarily operated, and therefore will gmerely release or otherwise operate the 'transmitter to send a signal 'of one round; ;the circuit-closer of another branch may be operated permanently and a signal-determining device provided for opening it or restoring it to normal when a signal'of two rounds has been sent by said transmitter; :the cir cuit-pioser's of other branches of the lcircuit may be operated permanently and signal-dete'rmining devices employed for =opening these branches of the circuit when four or five rounds.

Both forms of signal-determining devices for. thus mechanically and also electrically controlling the operation or the effect of the operation of the circuit-closers are herein adopted, and they may. and preferably will .be operated by the transmitting mechanism. In the circuit of the transmitter over which the code-signals are sent, and which may be operation of suitable non-interfering 'devices connected with the signal-transmitting imechanism, whereby the signal-transmitting mechanism is both non-interfering and successive, and the correct positive transmission of any signal selectedis absolutely insured. The signal-transmitting mechanism also 'the' transmitter-has sent a signal of three or' called a supervLsory-circuit, a non-interfen' ence magnet is provided for governing the has connected with it automatic means-for,

;circuit-closers for operating the startingconnecting a ground-circuit thereto, under certain condltions, or after a predetermined per od of time, so that the signal may be transmitted over a ground-circuit in casethe metallic circuit is out of order. The ground circuit will be connected to the transmittercircuit bet-ween the coils of the non-interference magnet, so that a coil of said magnet will be in circuitin either direction from said ground circuit,'and said ground circuit will be opened and closed simultaneously with the opening and closing of the signaling-contacts which will be connected in circuit between said coils, and a signal sent over the ground-circuit in either direction will therefore be non-interfering and successive, the same as though the ground-circuit was not used.

Means are provided for temporarily stopping the transmitting-mechanism to prevent it from running unnecessarily while attempts ing to send a signal over a disabled circuit.

Fig. 16 i s-a diagram of the circuit and devices of a part of an electric signalsystem, involving the employment 0 the signal-transmitting device. Fig. 17 is a front elevation of a modified formof s1 nal-transmitting apparatus, the non 'inter ering devices be ing omitted. F lg. 18 is a diagram of the circuit-connections of thetransmitter. In the embodiment of my-invention, as

here shown, for purposes of illustration, 111.

represents a spur-gear connected with a barrel m containing a main-spring. Said gearengages a spur-gear m, which engages a pinicn mi, secured to a shaft m", bearing a spur-gcaIn-m, which engages a pinion m, secured to a shaft 11f, bearing a spur-gear m, which engages a pinion m, secured to a shaft m bearlng an escape-wheel m, with which cooperates asuitable pallet. A detent m is secured to said shaft m which is normally engaged by an arm m of a lockinglever, which is secured to the pivot-shaft of v the armature-bearing lever m; of the starting-magnet m Said magnet 15 normally rlemiagnetized and its-armature is held in its retracted position by a suitable retractile-" spring m", and the locking-lever m is thereby normally held in engagement with the detent to hold the train at rest.

A signal-wheel m is secured to the shaft m", to be revolved thereby, and at the edge of said wheel a signal-key m is arranged,

which is mounted loosely on a pivot-stud n. Said key an insulating pin projectmg from it, which engages one member of a pair of contact pens m, ,'m arranged on an insulating-block m, and normally holds V 1 number and a blank space, and on each complete revolution it is designed to transmit said number; but it may be otherwise constructed. When the signal-key is permitted to co-act with the signal-wheel, it engages the signal-wheel and its movements are controlled thereby, being moved in one direction by the spring-acting contact-pen m, to

permit separation of the contact-pens, when entering one of the notches 'of said wheel,

and being moved in the opposite direction to'clcse-the contact-pens when the unnotched portion of the wheel passes by it. .The electric signaling-circuit including said contactpens is thus oper'ated'to send a signal.

To the signal-wheel shaft m, adisk m f is secured see' particularly Figs. 9 and "i0 which cooperates with an arm, mi", of the locking-lever; It has a two-stepped notch m, at a single point in its periphery, which is made quite long and adapted to receive apin m, extended laterally from said arm m, to'allow the locking-lever to move into locking position and engage the detent m; The locking-lever, when moved by the starting-magnet to disengage the detent m, is not permitted -to returnand reengage said detent and stop the train by reason of the unnotched portion of the disk moving be.- nea-th the pin m until said disk has-made a complete revolution. If the starting-magnetis operated only momentarily,as by a momentary closure of its circuit, as, for instance, bythe operation of a circuit-closer the train will be released and'the locking lever will be held in abnormal position by the disk until the notch m arrives in posit-ion beneath the pin m, when said pin will enter said notch and the locking-lever will resume its normal position and engage the detent m and thereby stop the train, and a signal of one round of the identifica tion number only will be transmitted. The

circuit-closer f is the one which is mornem. tarily closed to cause an on-duty s1gnal,.

as for instance, a signal of one-round to be sent, as shown in my application #555,603.

On one side of the disk m a pawl m is pivotally'motmted see Figs. 4 and 6, the en-' gagingend of which rests on the periphery disk m has a single notch m the radial side of which is arranged to be engaged by the pawl at or just before the end of the first round of the number transmitted,

see Fig: 9, so that in case the disk m is caused or permitted to turn more than one will operate to turn the disk m.

ioo

of another disk m, see dotted lines Fig.1, a mounted loosely on the shaft m, and said- The pawl 151" has an extension m which extends to the edge of the disk m or thereabout, and when said pawl enters the notch m in the disk m, its extension moves over the side of the long notch in the disk m and it is during this time that the extension on the pawl is engaged and held by the pin long enough to disengage the pawl from the notch of disk m. The pawl m and toothed-disk m constitute a clutch, and, in lieu thereof. a clutch of other suitable form may be employed. It. will be noted that the operation of the clutch is controlled by the starting-magnet. Said clutch is employed for the purpose of connecting the signal-determining devices with the transmittingmechanism. The disk m, as here shown,

is fastened to a pinion m, mounted loosely on the shaft m, which engages a spur-gear m secured to a sleeve m 'mounted loosely on shaft m.

As soon as the pawl disengages the disk, said disk and parts connected therewith and operated by it, are immediately restored or returned to normal position by a spring m connected at its outer end to the frame and at its inner end with the sleeve m. The

stop for limiting the return movement ofsaid parts is here shown as a pin m projecting from the side of the spur-gear m,

which engages a stop-arm m, fastened to the frame. In order to insure disengagement of the clutch after the transmitterhas operated long enough to send any possible signal, an emergency disengaging device is provided, see Fig. 11, consisting of a lever m pivoted to the frame,.having a projection which engages the periphery of a disk m, secured to the spur-gear m, and said disk has a raisedpo'rt-ion which will lift the lever m after the transmitter has transmitted five rounds of its code-signal number. The end of this lever m, when thus raised, will lie in the path of the, extension at of the pawl m thereby causing said pawl to disengage the disk m, allowing it to be restored in case for any reason it had not been previously disengaged at the end of five rounds ofthe signal-wheel.

Fastened to and mounted on the face of the spurrgearm is a cam-disk It, onwhich restsa pivoted lever h, which is connected by a rod it with a restoringdever it, adapted to engage and move a lever h, to

open a circuit-closer it, see Figs. 1, 15, and 17. This circuit-closer h is one which is automatically closed to cause an off-duty signal when a signal from some watch substation has not been received within a certain reasonable lapse of time. The camdisk 713 is so proportioned, and its movement so-controlled, that it will operate to raise the lever it and thereby open the circuit closer [L at or just before two rounds of the identification number have been transmitted. If the circuit of the starting-magnet is operated, as a result of the action of the circuit-closer 72, its armature will therefore remain in attracted position until said circuit-closer is thus opened mechanically by a rising movement of the lever and, upon the circuit being thus-opened, said armature is thereafter free to retractwhen the pin m of the locking-lever is next oppositethe-notch in the disk m and the codesignal sent will have included two rounds of the identification number. The cam-disk it" and means operated by it thus serve as and constitute one of the signal-determining devices, although its construction may-be modified in many ways.

I The circuitclosers for operating the branch or other circuits connected with the starting-magnet, which are employed for the purpose of operating the signal-transmitter to send other signals, vasthree rounds, four rounds, and five rounds, are all designed, when closed, to-remain closed permanently untilmanually or otherwise restored, and hence the armature of the starting-magnet will remain'in attracted position until said circuits are opened. As here shown such additional circuit-closers are represented at a, a. controlled by a relay 0:; and at 0, controlled by a slow-responding electromagnet' t in a. circuit controlled by a circuit-closer t, and at a, a, also controlled by said relay a, see Fig. 16, and

switches, as 1 y, and 7c, are employed for opening the circuits, each comprising a pair ofnormally closed contact-pens adapted to be separated to open the circuits by the o eration of the supervisory signal-transmitter. The circuit-closer a, a con-arises, as here shown-,s back contact tad armature of a. relay (a reference being had,to my application #555,601, and the armature of said relay normally occupies a semi attracte ed position, and when the circuit of said relay is broken or other trouble occurs whereby thearmature of said relay is caused to" fullyretract, a circuit of the start-ingma'g:

' net m ,-including the switch 2' will be closed,

and atrouble-signal transmitted which-is here represented, as a three-round signal. Said circuitwill remain closed until opened by the switch 2'. The circuit-closer t is designed to be operated automatically in the .usual manner by a thermostat'or sprinkler of ordinary construction, reference being had to my application #555,602, and when operated to close the circuit of the electromagnet t, and said electro-magnet t has a slow responding armature which controls the operation of the circuit-closer '0, of a circuit of the starting magnet m including a switch 7', so that said magnet m responds to a prolonged closure of the circuit-closer t, and its armature will remain in 'its attracted position until the circuit of the electro-Inagnet 25 is opened by the switch j.- An automatic fire-signal; is thus sent, being a signal of four-rounds. The relay a is also adapted to respond to an auxiliary fire-signal, reference being had to my app ications #555,601 and #555,602,- and its armature being normally in a semi-attracted position is adapted to be moved into attracted position upon the operation of an auxiliary firesignal device, and when so moved will tripthe circuit-closer a, (r of a circuit of the starting-magnet m ncluding a switch In,

and when closed will cause said magnet to respond, and the armature of sald magnet will remain attracted until the circuit in-.

with means operated. in conjunction with them serve as and constitute signaLdetermining devices by which the signal 'to be transmitted may be determined, yet my invention includes other forms of signaLdetermining devices arranged to be operated by the transmitting-mechanisin bywhich substantially the same results may be accomplished.

The cam-carrying shaft m is turned for the purpose of movingthe several cams to engage and open the several switches,

through the medium of a pin i see Fig. 13, which projects laterally from the cam-disk h, and engages a projection i on the edge of a disk 2', which is secured to said shaft m. The movement imparted to this camshaft may be more or less, according to the number of rounds, of the signal to be transmitted, and the cam-disks i, j, and k are arranged to engage their respective switches at different times, as, for instance, when the cam-disk h is moved in response to a signal ofmore than two rounds, as it will be if the armature of the starting-magnet remains in its attracted position, the pin '5 will turn the cam-carrying shaft to first bring the. cam-disk i intoengagement with the switch z, to open it, next the cam-disk '1" into en- 'the restoring-sp i as operated and the circuits including them opened, one after the oth'er,'and, when the branch-circuit which is closed by a circuitcloser that was operated to start the transmitter is opened, then the armature of the starting-magnet is free to be retracted and the transmittenstopped at the end of the round during or at the end of which the switch wasopened; 1

When the pawl m already described,

diseng'ages the disk m, said disk and pinion 30 on which it is mounted, and the spur-gearwheel m meshing with it, together with the cam-disk 71, mounted on said gearwheel, will be returned to normal position scribed, and the parts will be stoppedtby the aft 'esaidstop-pin m on thespur-gear en-' gaging the stop-arm m When a signal has been sent, as a result before-de- 35 of the operation of a circuit-closer which remains permanently closed until manually restored, it is obvious that the starting-magnet should not be placed again under the control of such circuit-closer until the latter has been properly restored. It is desirable, therefore, when such signals are sent, that the return movement of the camshaft m shall be manually controlled, so

that the switches which are opened by the cams shall not be closed again until after or simultaneously with the restoration of said circuit-closers. To accomplish this result, a disk 5 is secured to the front end by a sprin 2' and a cord i, or other means see Fig. l is connected to said catch-lever for the purpose of moving it to disengau'ge the notched disk. Thus, whenever any one of the three switches is operated to control the transmission of a three or four or fiveround signal, as the case may be, said switch, in particular, will be held open until it 'is permitted to return by a movement of the catch-lever,

In order thata differentiating signal-im- "pulsemay be transmitted with all the signals,-except the ,one-round signal, a long notch is formed on the signal-wheel m t 25 also engages the'signal-i-key when both the 5 arrives bene'a N lever, and while thejsigna'l-key is raised on but the signal-key. is prevented from falling into said notch whenonly one round is sent and in the following manner: A lever -n, pivoted at. n, has aprojeciion at one side which is held pressed into engagementwith a cam-disk n secured to the'side of the signal-wheel m or otherwise arranged to move with the signal-wheel. This cam-disk n has a long notch which corresponds to b the long. notch betW emrounds on thesignal-wheel, andit passes beneath the pro ection on lever n slightly retarded or out of step with the movement 'of' the longnotch on the signal 'wheel beneath the engaging portion .of the signal-key; but normally both long notches are arranged beneath-the engaging-projections of their cotiperating levers. The end of lever n "normally lies in the path of movement of thesignal-key, at which time said key is in raised position, with its circuit-contacts-closed, see'Figs, 1 and 17, said lever being held in such position independentlyof the signal-wheel by a pin n on the lockinglever-arm m which pin lever bearing it'and key are intheir normal positions. 7 When the locking-lever is moved, to disengage the stop-wheel, see Fig. 4', its pin is raised so as to disengage the-signal-key, but

the leve'r n will remain beneath said signalkey while the cam-disk a revolves with the signal-wheel until 'theraised 'port ion of thecam-disk arrives injposition toylift' said lever, see Fig; 9,- and this 'occurs'just after the end of the long notch on the signal wheel." The signal-keyis th'ns held mechanically. from co-acting with the signal- I wheel orlopening its' circuit-contacts iun'til signal-keytandon 'the first round of, the

The parts are so arranged that the cam-disk n arrive-sin po sition to permit. the lever n to fall and re- 55 sume its normal positipn, only after the last tooth' of the signal-wheel has passed beneath its key. If, however, the armature of the starting-magnet should remain in its 'attrae ted osition at the end of the first round, th 'mec anism will not then be stopped, nor

.wi l the signal-key be engaged orsupported by the locking-lever, hence as the long notch of the signal-wheel passes beneath the sig- .nal-key saidgkey will move into said long.

notch and 0 en itscircnit-conta'cts, so that, during the rst art of the second revolution of the signa -wheel, the circuit-contacts will beuopened'to' cause a long or diiferentiating impulse between the first and second rounds of the transmitter number. The cam-disk a would have permitted thelever n to resume its normal position during this time, but said l'v er, when falling, engages the end of the signal-key, see Fig. 10, and is thereby held, and when the signal-key is again moved by the signal-wheel-to re lease said lever, the signal-Wheel will have been. moved to the end of the long notch,

and the cam-disk a correspondingly moved, so, that said lever will be engaged by the high part of said cam-diskwhile the signalkey rests on the top ofthe first. tooth of the signal-wheel and before the first break of -.tion,o fthe signal to be transmitted, is controlled by magnet .of the said transmitter.

The multiple transmitter embodying .this invention is also here shown as provided with means wherebyit is absolutely-noninterferin and successive for all its sigthe operation of the startingn'als, so tiat, regardless of how-many of such-transmitters are opera-ted simultanelousl or one after another, on a circuit, no con s on will arise at the CQHtI'IIlSiEItIOH and no'signal will be lost.

Said pins m and m are ar- The pivoted latch-lever m is arranged in upright position at the side of the signalkey, and the pin m is made long enough to extend over both said lever and key. This latch-lever has a notch in, in its edge, and

notched portions of said key and lever are arranged so that the lower end ofthe notchthe upper end'of the notch in the key.

When the transmitter is at: rest the armad tureof the non-interference magnet is re 'f tracted, see Fig; l, as its'magnetis shunted from. the circuit of the shunt contacts m, and said pin. m lies in the path'of the" tends across the notch in the latch-'lever,-but at such time said latch-lever is held clear lever, which is made long enough to; extend over bothsaid lever and the signal-key.

When the locking-lever is moved to release the train the shunt m is first op'enedby it so that the armature of the non-interference magnet is immediately attracted, but the pin m1? will be caught-by the shoulder on the latch-lever and held until-said lever is raised by pin mi on the signal-wheel a moment after. whereupon the armature will be further attracted until the pin-.m is

in said latch lever,-see Fig; 4. When the train is released the pin n on the lockinglever is moved up above both the lever m and the signal-key, and said key is then heldby the pivoted-lever n, until said lever n is raised to disengage the signal-key after the long notch in the signal-wheel has passed. Vhen the first tooth of the signal-wheel. has also passed beneath the signal-key, ,then said key is free to move toward the .signalwheel, see Fig. 5,'and the upper end "oi: the notched portion thereof will more m'c'r the pinmflto thereby lock the nmr-inicrfercnce' lever m with the armature of the non-inand-hold it while the circuit is opened by the key.

, Should the circuit be in use, as by the sending of a signal from another transmitter at the time this transmitter is started, or should the signaling-circuit be opened duh ing the long interval of time 'prceedingthe L sending of the first signal-impulse of tin round, then the armature of the non-interference magnet will be or will remain reraised, so that the pin at will be opposite to or enter the notch in the latch lever m, andsaid pin m will also overlie the signalkey at a point above the notchin said key, to thereby hold the signal-key from .co-act-. ing with the signal-wheel. 'If the armature is in this retracted position, after the pin 'm has passed its cooperating projection in on the latch-lever m, then the notch in said latch lever will lock the lever m from moving into its most attracted-position to allow the signal-key to thereafter efi'ectively cooperate, with the signal-wheel until said latch-lever is again raised by the pin m upon another revolution of the signal-wheel,

and no signal will be sent meanwhile by reason of the signal-key being positively and mechanically held from opening the circuit uring such revolution. In order, thereore, to prevent a possibility of interference if the transmitter'is started while another signal is being sent, its non-interference devices areplaced under. the control of the circuit before thetransmitter opens the circuit and for a time longer than any closures during signals. To accomplish this result the pm 122," passes its engaging pro ection on latch-lever 4175" to unlock the non-interference lever m at such a tune before the signal-key could first open the circuit that the intervening time would be longer than the length of any closure of the circuit dur ing a signal'and ifthearmature drops away during this time, then the latch-lever will preventit returning until said latch-lever isagain moved by .pin m? 'just before the beginning of another round of the signal wheel, when the non-interference lever is again placed under'the control of the nonintcrfercnce magnet, as at the beginning of the operation. As the latch-lever is free to actat all times, except while being lifted by pin m", it can lock out the armature of the non-interference magnet at any time said armature is retracted during signaling, and, as said armature is unlocked and put under control of its signaling-circuit on every clcsn're of its signal-key, it will immediately on} out its signaling-device at any time that the signal is not being properly sent, as from any accidental or other break, and will' therefore prevent interference even though two or more transmitters had startedsimultanvously, or had sent more or less impulses in unison, as one of the tii-ins'mitters will be cut out the moment .the other opens the circuit out of unison therewith, lemiug the full control of the rircuit to one alone.

The clutch-pawl 111"" has arranged on it a form-ml extension mi", and the pin in bn the non-inieri'crenw lever In is adapted to be moved by said lever, when said lever is rein-acted under the conditions above-named, or equivalent conditions, into position to be engaged by said extension m"- so that its pawl inwill be moved by such engagement to unclutch the disk and permit the return of the signal-determining devices which are brought into action when the members 5 of the clutch are in engagement.

When the transmission of the signal is not interfered with, the non-interference lever remains attracted and said extension 111- passes over and free from engagement with the pin m". By providing this pin m and arranging it to engage the clutchmember and disengage the clutch in-this way provision is made for restoring parts of the transmitter to normal at the end of any signal, and for the re-setting of parts in case the signal is interfered with when but partiallytransmitted, as, for instance, when two rounds of a three, four, or fiveround signal have been transmitted, and, when the parts are reset, the operation will be repeated until the complete signal is sent for which the transmitter wasstarted. It will thus be observed that the clutch is controlled not only by the non-interference magnet for the purpose of disengaging" it when the signal is not properly sent, butalso by the starting-magnet to disengage it when the proper number of rounds have been correctly sent.

For the purpose of applying a ground connection when. the transmitter is operated upon-a continuously broken circuit, so that the signal may-be sent over aground cir: cuit, a circuit-"controlling device is provided at the transmitter, so that, whenever thecircuit breaks and stays broken-longer than any break which would be causedw by a signal, the circuit-controlling-devicev will be operated and a ground connection established over which the signal will be sent:

Referring to Figs/1, 7 and 8 m represents a contact-pen which is connected with a ground branch circuit. It is attached to alever m pivoted at m", said lever having a bifurcated extension m, which is engagegl by a pin m on anarm m pivoted at m, and to said pivot-shaft a plate in is fixed, having its end formed with a series of steps m, and having on its side two pins m m, arranged a short distance apart, to be has a pin m adapted to be moved into position 'to engage the endof va spring-catch 5 m attached to the locking-lever arm m As the pinion m rerolves, the pin borne by it first engages the pin m and acts to move the plate a short distance, but far enough for the first step thereon to engage the pin er 6n the non-interference, lever m, and inch-engagement will be effected if said nonter'ference lever is in its elevated position,-, f

.caused by the retraction of the armature of the non-interference magnet, but not'other-.

5 wis n-casesaidlever is notin its elevated positiongthe plate; when thus moved, will be netfirned to its normal position bye spring attached to has soon as the pin m passes by the pin m and. releases it. Ing the normal operation of the transmitter, the in:

plate will thus be moved. repeatedly a short distance andrturned to normal'during each revdlution of the pinion. 1

If the non-interference lever isi elevated position when the plate is moved,'as it will b'incase the circuit is continuously broken during or prior to the first revolution of the pinion, the first step of the plate will engage the pin m, and, during the next revolution, the pin m will engage pin m to further move the plate m, and the second steof theplate will engage-said pin m, and, at the same time, the pin at will pass over the end ofthe spring-catch m on the locking-lever, so that the plate will then 3 "second estep, and such additional upward movement of the lever will cause the pin m? to engage the arm m on the pallet and stop the train while in such most upward i position. As soon as-the ground connection is thus established, lf 4h1 Cll011itflS scl'ose'd."

thereby over either s idel-of theline'to-the battery and free from interference, the armature of the nondnterferencemagnet will be immediately attracted and the lever. m-moved downward far enough in ,disengage the arm'onthe palletg permitting the 5 train to continue its operation, but the ground plate will still remaih locked in ahnormal position by the spring-arm on' the locking-'leve'rg-keeping its groundin operative connection with the slgna-ling-contacts 11 and will be opened and closed by them simultaneously with their operation one with relation with the other; in o-therwords,

. when the line contacts areclose'd'with'each other, they will-"also close connection withsuccessively engaged by a pin on on a hub pm of the pinion m. ,Said plate m also the ground,-and,,-when they open or'separate" f from each other, they. will also open or sepa} 'rate their connection with tl1e ..ground, so

that a signal may be transmitted it either as the.signalii1g-contacts-are'ponnected in circuit between the coils ofthe non-interference magnetfand thereforexmeor the'other 12E- coil will be in either 'groun'd circuitthat may be inade by-the operation ofthe' transmitter. 1

At the completion'iof the signal the locking-lever is permitted tonnesume its normal we position by the retraction of thearmature ,of the starting-magnet, and the ground plate thereby released and permitted to resume its normal position, disconnecting the ground. J H i In case the transmitter is started while another signal'is-being transmitted, and the circuit intermittently opened andclosed, then the ground will not be put on' for the reason that the non-interference magnet,- which may hold the plate m at its first step, will be attracted at a closure of the circuit made by the si nal being transmitted', 'whichwill be ma e before the plate can be caused to make its second step, as the parts will be so related and arranged. that the time'elapsingbetween two possible successive-steps will be much longer than the longest break in the signaling-circuit caused by any signal. I

m and m represent radial arms on the winding-device of the main spring ofnthe transmitter to which handles or levers may be connected, either of which 'may be operated to wind said spring. 7
